TECHNICAL FIELD

The present invention relates to amino alcohol derivatives or phosphonic acid derivatives having excellent immunosuppressive activity, pharmacologically acceptable salts of amino alcohol derivatives or phosphonic acid derivatives, pharmacologically acceptable esters of amino alcohol derivatives or phosphonic acid derivatives, and to pharmaceutical compositions comprising said compounds as an active ingredient.

The present invention also relates to pharmaceutical compositions comprising, as active ingredients, one or more immunosuppressants and one or more compounds selected from the group consisting of amino alcohol derivatives or phosphonic acid derivatives having excellent immunosuppressive activity, pharmacologically acceptable salts thereof, and pharmacologically acceptable esters thereof. Said compositions are useful as preventive or therapeutic agents for autoimmune diseases such as rejection of transplanted tissues or cells, rheumatoid arthritis, or other immune activity-related autoimmune diseases.

BACKGROUND OF THE INVENTION

In the past, anti-inflammatory agents such as steroids have been used for inflammatory reactions arising from abnormal immune response in treatment of immune-related diseases such as rheumatoid arthritis and other autoimmune diseases. These are, however, a symptomatic therapy, but not a fundamental remedy.

Furthermore, it has been reported that immune system abnormalities are also involved in the development of diabetes and nephritis, but agents that improve these abnormalities have not yet been developed.

On the other hand, it is critical to develop an approach to suppress the immune response for avoiding rejection in transplanted tissues or cells, as well as for treating and preventing various autoimmune diseases.

However, immunosuppressants, such as cyclosporin A (CsA) and tacrolimus (TRL) that have been known in the past, are known to show toxicity against the kidney and liver. Although treatments that also use steroids are commonly used for the relief of such adverse reactions, it is presently the case that such agents have not necessarily led to producing a satisfactory immunosuppressive effect without showing any adverse reaction.

In light of this background, it has been attempted to find excellent compounds with immunosuppressive effects that are less toxic.

As to immunosuppressants, the following compounds are known.

-   (1) Compounds having the general formula (a) disclosed in WO     94/08943 (page 371)

{in the above compounds (a),

R_(x) represents a straight or branched carbon chain which may optionally be substituted with one or more substituents [said chain may contain a double bond, a triple bond, an oxygen atom, a sulfur atom, a group of formula —N(R_(x) ⁶)— (wherein R_(x) ⁶ represents a hydrogen atom), an arylene group which may optionally be substituted with one or more substituents, or a heteroarylene group which may optionally be substituted with one or more substituents, and may contain, at the end of said chain, an aryl group which may optionally be substituted with one or more substituents, a cycloalkyl group which may optionally be substituted with one or more substituents, or an aromatic heterocyclic group which may optionally be substituted with one or more substituents], and

The compounds of the present invention, however, contain one —CH₂OR³ group and one lower alkyl group as essential groups substituted on the same carbon atom and are different from the compounds (a) in these substituents.

The compounds of the present invention, however, contain one —CH₂OR³ group and one lower alkyl group as essential groups substituted on the same carbon atom and are different from the compounds (c) in these substituents.

In addition, above compounds (c) contain a phenyl group between the —(CH₂)₂— group and the —CO—(CH₂)₄ group as an essential group in the basic skeleton. The compounds of the present invention contain a heterocyclic group such as a furyl group, a pyrrolyl group, or a pyrrolyl group having a substituent on the nitrogen atom instead of the phenyl group of compound (c) and are different from the compounds (c).

B group, at a volume of 10 ml/kg once daily for 10 successive days.

Cyclosporin A suspended solution plus 0.5% MC solution, tacrolimus plus 0.5% MC solution, and compound B plus 0.5% MC solution were orally co-administered at a volume of 10 ml/kg once daily for 10 successive days starting on the day of injection of spleen cells in the cyclosporin A, tacrolimus, and compound B administered groups, respectively.

In both the “same strain group” (BDF1 mice treated with spleen cells of BDF1 mice but not treated with the compound) and “control group” (BDF1 mice injected spleen cells of C57BL/6 mice, but not treated with the compound), 0.5% MC solution was orally administered.

-   (4) Determination Methods of Inhibitory Activities of Compounds     Against GvHD

Body weight was determined and spleens were weighed, and “spleen weight compensated for the body weight following injection of GvHD” was calculated by dividing the spleen weight by the body weight. Average “spleen weight compensated for body weight in the same strain group” was subtracted from the individual “spleen weight compensated for body weight following injection of GvHD”. The inhibitory activities of compounds were calculated from the ratios of individual “spleen weight compensated for body weight following injection of GvHD” to the average “spleen weight compensated for body weight following injection of GvHD” in the control group.
